spiecatien frming pm of Letters Patent N. 103,5, dated May el, Isvo.-

Be it known that I, W. H. SHOCK, of Washington, in the county of Washington and District of Columbia, have invented certain new ad -useful Improvements in Projectiles for Fire-Arms; and I do hereby declare that thel following is a full, clear, and exact-description thereof, reference being had to the accompanying drawings, making part of this specification, and to the letters of reference marked thereon, like letters indicating like parts Wherever they occur.

of the same, as hereinaftery more fully ex plained.

Figure 1 isa longitudinal section of -acartridge for small-arms with my improvement applied. Figs. 2 and 3 are longitudinal sec` -tions ofthe projectile detached, and Fig. 4 is an edge view of the button or Wad detached.

The object of my invention is to produce a projectile which will, when fired, have amore accurate iiight with a atter trajectory, and

which shall be more certain to avoid tumbling, and have less resistance to its passage through theair.v

To accomplish these objects I construct my projectile with a hole extending centrally through it from front to rear, as shownin the drawings, in which A represents the projectile. -Thisholeor passage e, I make more or lessV conical, it being larger at the rear end than at the front, by which means the front end of the projectile is made the heaviest, and Will therefore 'keep foremost in its flight. At the same time this hole e permits a column of air to pass through the prpjectile in its flight, which thereby prevents the formation of a vacuum-in its rear, whereby its liight is increased. Y

In order to prevent the escape ofV the propelling-gases through the hole e, -I provide a button or wad, B, of a size and shape to fit against the rear end 'of the ball and cover the hole, as represented in Fig. 1, the Wad beingv shown detached in Fig. 4., This wad or butexpedient in practice.. To, enable others skilled in the lart to con- It is obvious that my Improvement may be applied to any style of elongated projectile, the front end being pointed, as in Fig. 1, or more rounded', as in Fig. 2, or flattened, as in Fig. 3. It may also be applied to projectiles for either large or small arms, the principle being the same in both. Bythis plan I produce a projectile that will not tumble, but Y keep end on, and that will passt-hrough the air with the least possible amount of resistance, and consequently obtain greater range andA accuracy.

, I am aware' that it has been proposed t make projectiles with a hole of uniform diameter through them, and also to-make them with` a .conical hole, .but not with the center of gravityin front of the center of length, asin mine, and therefore I do not claim, broadly, a pro- .ectile with a longitudinal opening through it;

ut f

- What I do claim is-- A projectile in which shall be combined the 7 following elements or features: first, it shall be elongated; second, have a conical opening extending through it from front to rear, and of suchsize and form as to cause the center of gravity of said projectile to be in front of WM.
